BUILDERS COMBINED TOOL.

SPECIFICATON forming part of Letters Patent No. 533,200, dated January 29, 1895. Application led November 5, l 894:. Serial No. 527.878.` (No model.)

To @ZZ whom t may concern:

Be it known that I, EDWIN E. NUHN, a citizen of the United States, and a resident of Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combined Builders Tools, of which the following is a specification'.

The object of my invention is to combine in a single instrument a try-square, bevel, spirit ro level and gage.

The invention willbe first fully described in connection with the accompanying drawings, and then particularly referred to and pointed out in the claims.

Referring to' the drawings, in which like parts are indicated by similar reference letters wherever they occur throughout the various views: Figure l is a perspective view of the instrument with the gage plates partially 2o drawn out. Fig. 2 isa oentrallongitudinal section of the saine, the parts being in the same position, except the blade, which is shown parallel to the sides of the stock. Fig. 3ris a side elevation looking at the reverse side from the z 5 view shown in Fig. l, with the gage plates pushed into `the closed position and the blade in full line in the same position as in Fig. 2, and in dotted line, in the position the blade .occupies when folded. Fig. 4 is a plan View 3o of a bevel blade which may, when desired, be

substituted for the try-square and bevelblade shown in the preceding figures. Fig. 5 is a detailed inverted plan view of vone of the metal plates at the front end of the stock. The body of the stock, A, is, for lightness, preferably made of hard wood, longitudinally recessed to receive the sliding gage plates, B and B. The gage end is armed with a metal plate, O, which iscut away upon one edge to 4o pass the gage plates, and also has a notch, c, in the bottom of the recess to pass the gage pins, b and b. The heel of the stock is routed upon one side to receive the metal plate, O', which has its rear edge cut away, as seen clearly in Figs. 2 and 3, so that the heads of the gage pins, b and b', are easily accessible for drawing out either one or other of the gage plates. The opposite side of the stock from plate O has a circular recess to receive the circular 5o metal plate, O2, which has a downwardly proj ectin g screw threaded hub extending through the wooden portion of the stock, and above the gage plate, B. This hub is fitted with a screw having across head, O3, which comes within the recess and by turning which the gage plates may be released to allow them to be drawn out, or pushed in and locked in any desired position.

The opposite end of the stock, A, has aprojecting tenon, a, and one edge of the stock is 6o centrally slotted in line with the face of the tenon to permit the try-square blade, D, to

fold to the position shown in dotted line Fig.

3. Upon one side of the tenon is secured a metal plate, D', which has a screwltlireaded 65 perforation in it to receive the screw threaded shank of the binding screw, D2, which passes through an angle plate, D3, through a circular opening in the blade, D, and the tenon, a, the plate, D3, being secured to the end of the 7o stock by screws passing through the angle plate and .into the end of the stock, as seen in dotted line Fig. 3.

The semi-circular forward edge of the plate, D3, is beveled and has marked upon its beveled edge Fig. 3 a graduated scale indicating the different angles to which the blade, D, may be set, and these angles are to be determined by the index line, d on the blade,

D, as seen in Fig. 3. This plate, D3, has pro- 8o jecting from its inner face a stop, d', against which the edge of the blade, D, bears when it is, as shown in Fig. l, set at right angles to the edge of the stock to be used as an ordinary try-square.

One edge of the stock is recessed to receive the spirit level, F, the sides cut away and a semiecircular opening through it, like the or` dinary spirit level, to throw light upon the glass tube holding the mercury or spirits. 9o

The pin, b, secured in the outer end of the gage plate, B, projects up through the longitudinal slot in the gage plate, B', both the points, ZJ and b', being in the same plane and either one or both adapted for use as desired. In Figs. l and 2 they are shown drawn out and clamped in the position to gage a` tenon or mortise, both scribes' being made at the same time. If it is only desired to make one scribe, the plate,B, alone is pulled out,while roo the plate, B, is left in its closed position.. If it is desired to use the tool as an ordinary bevel,

the blade, D, may be removed and the bevel blade, D4, Fig. 1i, substituted in place of it.

Upon the end of the blade, D, are riveted, or otherwise secured, upon one or both sides, bars, dwhich maybe used to gage the thickness of material, the blade being graduated in inches and fractions of inches upon opposite sides, but these bars may be omitted if desired.

It is evident that the tool may be used for all purposes for which a try square, bevel, spirit level or gage may be used. To be used as a try square, the blade, D, is brought aroun d to the position shown in Fig. l, the edge of the blade abutting against the stop, d', projecting inwardly from plate, D3. lf it is desired to use it as a bevel, the binding screw, D2, is loosened, the blade thrown around to the desired angle, as indicated upon the index upon the end of plate, D3, and again tightened. 'llo adjust the blade s0 as to set rafters or other timbers, to the desired angle, the blade,D, is iiXed to the angle desired, the stock laid upon the edge opposite the spirit level, when the blade will indicate the angle that the diagonal timbers should be placed relative to the rafters or other cross timbers of the building, and it is evident that the stock may be used as an ordinary spirit level, to bring the horizontal timber to a true position. When the tool is to be put away, the gage plates are pushed in and the blade folded to the position shown in dotted line, Fig. 3, when the tool will occupy less space than the ordinary try square.

There may, of course, be many mechanical changes made in the different parts without varying the spirit or scope of my invention and, hence, without limiting myself to the specific details of construction shown.

What l claim as new, and desire to secure by Letters Patent, is

l. The combination, in a tool ofthe character described, of the stock, longitudinally recessed to receive the sliding gage plates, the gage plates fitted to slide in said recess, a set screw to hold the adjustment of said plates, the try square and bevel blade fitted in the opposite end of the stock, a stop to set the blade to the right angled position, and a binding screw to clamp the blade when set, substantially as shown and described.

2. The combination of the stock, longitudinally recessed to receive the sliding gage plates, the gage plates fitted to slide in said recess, each plate having scribe pins on the outer end and one of said plates being longitudinally slotted to pass the scribe pin upon the opposite plate, a set screw having its head recessed into one side of the stock to hold the gage plates in position, the opposite end of the stock having a tenon formed upon it and one edge slotted to admit of the blade folding partially within the stock, a metal plate upon one side of the tenen having ascrew threaded opening, an angle plate upon the opposite side perforated to register with said threaded opening, and having its edge beveled and marked to indicate the different degrees of a circle, the blade, D, fitted between the said angle plate and adjacent face of the tenen and having an index mark, CZ, and a binding screw, D2, passing through plate, D3, the blade, D, and engaging the screw threaded openingin the plate upon the opposite side, for the purpose of holding the adjustment of the blade, D, substantially as shown and described.

3. The combination ofthe stock, longitudinally recessed to receive the sliding gage plates, slotted upon one edge to receive the try square blade when folded, a stop in the slot to set the try square blade to the right angle position, the spirit level fitted in the opposite edge of said stock, the blade, D, fitted in one end of the stock, with its gage plates fitted to slide in and out ofthe opposite end, and means such as shown to hold the adjustment of the blade and gage plates, substantially as shown and described.

4. Asanew article of manufacture, the combined try square, bevel, gage and spirit level, consisting substantially of the stock, A, recessed to receive the sliding gage, slotted upon one edge to allow the blade to fold, having a stop in the slot to set the try square blade to the right angle position, and aspirit level secured in the opposite edge from that slotted to receive the blade of the try square, the adjustable try square blade, D, fitted in the end of the stock, and the screws to hold the adjustment of the blade and gage plates, said screws being below the sides of the stock, the whole constructed and combined substantially as hereinbefore set forth.
